Kanban Orchestrator — Decomposition Playbook

The core worker lifecycle (including the kanban_create fan-out pattern and the "decompose, don't execute" rule) is auto-injected into every kanban process via the KANBAN_GUIDANCE system-prompt block. This skill is the deeper playbook when you're an orchestrator profile whose whole job is routing.

When to use the board (vs. just doing the work)

Create Kanban tasks when any of these are true:

1. Multiple specialists are needed. Research + analysis + writing is three profiles.
2. The work should survive a crash or restart. Long-running, recurring, or important.
3. The user might want to interject. Human-in-the-loop at any step.
4. Multiple subtasks can run in parallel. Fan-out for speed.
5. Review / iteration is expected. A reviewer profile loops on drafter output.
6. The audit trail matters. Board rows persist in SQLite forever.

If none of those apply — it's a small one-shot reasoning task — use delegate_task instead or answer the user directly.

The anti-temptation rules

Your job description says "route, don't execute." The rules that enforce that:

• Do not execute the work yourself. Your restricted toolset usually doesn't even include terminal/file/code/web for implementation. If you find yourself "just fixing this quickly" — stop and create a task for the right specialist.
• For any concrete task, create a Kanban task and assign it. Every single time.
• If no specialist fits, ask the user which profile to create. Do not default to doing it yourself under "close enough."
• Decompose, route, and summarize — that's the whole job.

The standard specialist roster (convention)

Unless the user's setup has customized profiles, assume these exist. Adjust to whatever the user actually has — ask if you're unsure.

Decomposition playbook

Step 1 — Understand the goal

Ask clarifying questions if the goal is ambiguous. Cheap to ask; expensive to spawn the wrong fleet.

Step 2 — Sketch the task graph

Before creating anything, draft the graph out loud (in your response to the user). Example for "Analyze whether we should migrate to Postgres":

T1  researcher        research: Postgres cost vs current
T2  researcher        research: Postgres performance vs current
T3  analyst           synthesize migration recommendation       parents: T1, T2
T4  writer            draft decision memo                       parents: T3

Show this to the user. Let them correct it before you create anything.

Step 3 — Create tasks and link

t1 = kanban_create(
    title="research: Postgres cost vs current",
    assignee="researcher",
    body="Compare estimated infrastructure costs, migration costs, and ongoing ops costs over a 3-year window. Sources: AWS/GCP pricing, team time estimates, current Postgres bills from peers.",
    tenant=os.environ.get("HERMES_TENANT"),
)["task_id"]

t2 = kanban_create(
    title="research: Postgres performance vs current",
    assignee="researcher",
    body="Compare query latency, throughput, and scaling characteristics at our expected data volume (~500GB, 10k QPS peak). Sources: benchmark papers, public case studies, pgbench results if easy.",
)["task_id"]

t3 = kanban_create(
    title="synthesize migration recommendation",
    assignee="analyst",
    body="Read the findings from T1 (cost) and T2 (performance). Produce a 1-page recommendation with explicit trade-offs and a go/no-go call.",
    parents=[t1, t2],
)["task_id"]

t4 = kanban_create(
    title="draft decision memo",
    assignee="writer",
    body="Turn the analyst's recommendation into a 2-page memo for the CTO. Match the tone of previous decision memos in the team's knowledge base.",
    parents=[t3],
)["task_id"]

parents=[...] gates promotion — children stay in todo until every parent reaches done, then auto-promote to ready. No manual coordination needed; the dispatcher and dependency engine handle it.

Step 4 — Complete your own task

If you were spawned as a task yourself (e.g. planner profile was assigned T0: "investigate Postgres migration"), mark it done with a summary of what you created:

kanban_complete(
    summary="decomposed into T1-T4: 2 researchers parallel, 1 analyst on their outputs, 1 writer on the recommendation",
    metadata={
        "task_graph": {
            "T1": {"assignee": "researcher", "parents": []},
            "T2": {"assignee": "researcher", "parents": []},
            "T3": {"assignee": "analyst", "parents": ["T1", "T2"]},
            "T4": {"assignee": "writer", "parents": ["T3"]},
        },
    },
)

Step 5 — Report back to the user

Tell them what you created in plain prose:

I've queued 4 tasks: - T1 (researcher): cost comparison - T2 (researcher): performance comparison, in parallel with T1 - T3 (analyst): synthesizes T1 + T2 into a recommendation - T4 (writer): turns T3 into a CTO memo

The dispatcher will pick up T1 and T2 now. T3 starts when both finish. You'll get a gateway ping when T4 completes. Use the dashboard or hermes kanban tail <id> to follow along.

Common patterns

Fan-out + fan-in (research → synthesize): N researcher tasks with no parents, one analyst task with all of them as parents.

Dedicated project swarm: For a major project, create one board and one role-profile roster rather than mixing work into default. Example software roles: projectpm, projectbackend, projectfrontend, projectops, projectqa, projectdomain, projectreviewer. For business/operations projects, use domain roles such as projectpm, projectresearcher, projectops, projectfinance, projectcompliance, projectwiki, projectreviewer. Seed broad audit/spec tasks in parallel, then one synthesis task with all audits as parents, then one reviewer gate as the final child. Use worktree for tasks that may edit repos and scratch for planning/research/wiki-audit tasks. If the installed Hermes lacks a top-level hermes swarm command, this board+profiles pattern is the swarm. See references/project-swarm-board-pattern.md for a reusable command recipe plus Astral Hermes and Salmon Business examples.

Pipeline with gates: pm → backend-eng → reviewer. Each stage's parents=[previous_task]. Reviewer blocks or completes; if reviewer blocks, the operator unblocks with feedback and respawns.

Same-profile queue: 50 tasks, all assigned to translator, no dependencies between them. Dispatcher serializes — translator processes them in priority order, accumulating experience in their own memory.

Human-in-the-loop: Any task can kanban_block() to wait for input. Dispatcher respawns after /unblock. The comment thread carries the full context.

Pitfalls

Profile clone may not clone OAuth auth state. hermes profile create NAME --clone can copy config/env/skills while leaving provider OAuth state behind. Kanban workers for cloned profiles may crash immediately with messages like No Codex credentials stored even though hermes profile list shows the right model. Copy ~/.hermes/auth.json into each new profile home (chmod 600) or re-run provider login for the profile, then smoke-test with hermes --profile NAME chat -q 'Reply with exactly: ok' --provider openai-codex -m gpt-5.5 -Q before trusting the dispatcher.

Reassignment vs. new task. If a reviewer blocks with "needs changes," create a NEW task linked from the reviewer's task — don't re-run the same task with a stern look. The new task is assigned to the original implementer profile.

Argument order for links. kanban_link(parent_id=..., child_id=...) — parent first. Mixing them up demotes the wrong task to todo.

Don't pre-create the whole graph if the shape depends on intermediate findings. If T3's structure depends on what T1 and T2 find, let T3 exist as a "synthesize findings" task whose own first step is to read parent handoffs and plan the rest. Orchestrators can spawn orchestrators.

Tenant inheritance. If HERMES_TENANT is set in your env, pass tenant=os.environ.get("HERMES_TENANT") on every kanban_create call so child tasks stay in the same namespace.
